Codonopsis Radix is a traditional tonic medicine commonly used in China, which has the effects of strengthening the spleen and tonifying the lung, as well as nourishing blood and engendering liquid. The chemical constituents of Codonopsis species are mainly polyacetylenes, alkaloids, phenylpropanoids, lignans, terpenoids and saponins, flavonoids, steroids, organic acids, saccharides, and so on. Modern pharmacological studies showed that Codonopsis Radix also has a variety of pharmacological effects such as enhancing body immunity, protecting gastrointestinal mucosa and resisting ulcers, promoting hematopoietic function, regulating blood sugar, and delaying aging. In this paper, the chemical constituents of Codonopsis species and the pharmacological effects of Codonopsis Radix were summarized, and on this basis, the quality markers of Codonopsis Radix were analyzed. It was predicted that lobetyolin, tangshenoside I, codonopyrrolidium A, and the oligosaccharides were the possible Q-markers of Codonopsis Radix. This paper will provide scientific references for the quality evaluation and profound research and the development of Codonopsis Radix.

To solve the serious problem of stem and leaf shading in the middle and late stage of traditional flat planting of Codonopsis pilosula, this study analyzed the effects of different stereoscopic traction heights on the photosynthetic characteristics and growth of C. pilosula and explored the optimal traction height to improve the yield and quality of C. pilosula. The experiment designed three stereo-scopic traction heights [H1(60 cm), H2(90 cm), and H3(120 cm)] with natural growth without traction as the control(CK). The results showed that the increase in stereoscopic traction heights broadened the growth space of stems and leaves of C. pilosula, enhanced the ventilation effect, significantly increased the average daily net photosynthetic rate of C. pilosula, promoted the absorption of intercellular CO_2, decreased the transpiration rate, and reduced the evaporation of water. Moreover, it effectively avoided the problem of weakened photosynthesis, maintained the carbon balance of individual plants, and promoted the growth and development of the C. pilosula roots. In terms of the seed yield of C. pilosula, it was ranked as H2>H1>H3>CK. To be specific, H1 increased by 213.41% compared with CK, H2 increased by 282.43% compared with CK, and H3 increased by 133.95% compared with CK. The yield and quality of C. pilosula were the highest in the H3 treatment group, with the fresh yield of 6 858.33 kg·hm~(-2), 50.59% higher than CK, dry yield of 2 398.33 kg·hm~(-2), 76.54% higher than CK, and lobetyolin content of 0.56 mg·g~(-1), 45.22% higher than CK. Therefore, the stereoscopic traction height has a great influence on the photosynthetic characteristics, yield, and quality of C. pilosula. Particularly, the yield and quality of C. pilosula can be optimized and improved in the traction height treatment of H3(120 cm). This planting method is worth popularizing and applying in the cultivated management of C. pilosula.

Alkaloids are a class of naturally occurring bioactive compounds that are widely distributed in various food sources and Traditional Chinese Medicine. This study aimed to investigate the therapeutic effects and underlying mechanisms of alkaloid extract from Codonopsis Radix (ACR) in ameliorating hepatic lipid accumulation in a mouse model of non-alcoholic fatty liver disease (NAFLD) induced by a high-fat diet (HFD). The results revealed that ACR treatment effectively mitigated the abnormal weight gain and hepatic injury associated with HFD. Furthermore, ACR ameliorated the dysregulated lipid metabolism in NAFLD mice, as evidenced by reductions in serum triglyceride, total cholesterol, and low-density lipoprotein levels, accompanied by a concomitant increase in the high-density lipoprotein level. ACR treatment also demonstrated a profound anti-oxidative effect, effectively alleviating HFD-induced oxidative stress and promoting ATP production. These effects were achieved through the up-regulation of the activities of mitochondrial electron transfer chain complexes I, II, IV, and V, in addition to the activation of the AMPK/PGC-1α pathway, suggesting that ACR exhibits therapeutic potential in alleviating the HFD-induced dysregulation of mitochondrial energy metabolism. Moreover, ACR administration mitigated HFD-induced endoplasmic reticulum (ER) stress and suppressed the overexpression of ubiquitin-specific protease 14 (USP14) in NAFLD mice. In summary, the present study provides compelling evidence supporting the hepatoprotective role of ACR in alleviating lipid deposition in NAFLD by improving energy metabolism and reducing oxidative stress and ER stress. These findings warrant further investigation and merit the development of ACR as a potential therapeutic agent for NAFLD.

This study aims to mine the transcription factors that affect the genuineness of Codonopsis pilosula in Shanxi based on the transcriptome data of C. pilosula samples collected from Shanxi and Gansu, and then analyze the gene expression patterns, which will provide a theoretical basis for the molecular assisted breeding of C. pilosula. Gene ontology(GO) functional annotation, conserved motif prediction, and gene expression pattern analysis were performed for the differential transcription factors predicted based on the transcriptome data of C. pilosula from different habitats. A total of 61 differentially expressed genes(DEGs) were screened out from the transcriptome data. Most of the DEGs belonged to AP2/ERF-ERF family, with the conserved motif of [2X]-[LG]-[3X]-T-[3X]-[AARAYDRAA]-[3X]-[RG]-[2X]-A-[2X]-[NFP]. Forty-three of the DEGs showed significantly higher gene expression in C. pilosula samples from Shanxi than in the samples from Gansu, including 11 genes in the AP2/ERF-ERF family, 5 genes in the NAC fa-mily, 1 gene in the bHLH family, and 2 genes in the RWP-RK family, while 18 transcription factors showed higher expression levels in the samples from Gansu. GO annotation predicted that most of the DEGs were enriched in GO terms related to transcriptional binding activity(103), metabolic process(26), and stress response(23). The expression of transcription factor genes, CpNAC92, CpNAC100, CpbHLH128, and CpRAP2-7 was higher in the samples from Shanxi and in the roots of C. pilosula. CpNAC92, CpbHLH128, and CpRAP2-7 responded to the low temperature, temperature difference, and iron stresses, while CpNAC100 only responded to low temperature and iron stresses. The screening and expression analysis of the specific transcription factors CpNAC92, CpNAC100, CpbHLH128, and CpRAP2-7 in C. pilosula in Shanxi laid a theoretical foundation for further research on the mechanism of genuineness formation of C. pilosula.

This paper aims to explore the activity of Codonopsis canescens extract against rheumatoid arthritis(RA) based on the Toll-like receptors(TLRs)/mitogen-activated protein kinases(MAPKs)/nuclear factor kappa B(NF-κB) signaling pathways and its mechanism. The ultra-performance liquid chromatography-quadrupole time-of-flight/mass spectrometry(UPLC-Q-TOF-MS) was used to identify the components of C. canescens extract. Forty-eight male SD rats were randomly divided into six groups, namely the normal group, the model group, the methotrexate(MTX) tablet group, and the low, medium, and high-dose C. canescens extract(ZDS-L, ZDS-M, and ZDS-H) groups, with 8 rats in each group. The model of collagen-induced arthritis in rats was induced by injection of bovine type Ⅱ collagen emulsion. MTX(2.5 mg·kg~(-1)), ZDS-L, ZDS-M, and ZDS-H(0.3 g·kg~(-1), 0.6 g·kg~(-1), and 1.2 g·kg~(-1)) were administrated by gavage. Rats in the normal group and the model group received distilled water. MTX was given once every three days for 28 days, and the rest medicines were given once daily for 28 days. Body weight, degree of foot swelling, arthritis index, immune organ index, synovial histopathological changes, and serum levels of tumor necrosis factor-α(TNF-α), interleukin-1β(IL-1β), and interleukin-6(IL-6) were observed. Protein expressions of TLR2, TLR4, NF-κB p65, p38 MAPK, and p-p38 MAPK in rats were determined by Western blot. Thirty-four main components were identified by UPLC-Q-TOF-MS, including 15 flavonoids, 7 phenylpropanoids, 4 terpenoids, 4 organic acids, 2 esters, and 2 polyalkynes. As compared with the normal group, the body weight of the model group was significantly decreased(P<0.01), and foot swelling(P<0.05, P<0.01), arthritis index(P<0.01), and the immune organ index(P<0.01) were significantly increased. The synovial histopathological injury was obviously observed in the model group. The serum levels of inflammatory factors TNF-α, IL-1β, and IL-6 were significantly increased(P<0.01), and the protein expression levels of TLR2, TLR4, NF-κB p65, p-p38 MAPK/p38 MAPK in the synovial tissue were significantly increased(P<0.01) in the model group. As compared with the model group, the body weights of the ZDS dose groups were increased(P<0.01), and the degree of foot swelling(P<0.01) and the arthritis index were decreased(P<0.05, P<0.01). The immune organ index was decreased(P<0.01) in the ZDS dose groups, and the synovial tissue hyperplasia and inflammatory cell infiltration were alleviated. The serum levels of TNF-α, IL-1β, and IL-6 were significantly decreased(P<0.05, P<0.01), and the protein expression levels of TLR2, TLR4, NF-κB p65, p-p38 MAPK/p38 MAPK were decreased(P<0.05, P<0.01) in the ZDS dose groups. C. canescens extract containing apigenin, tricin, chlorogenic acid, aesculin, ferulic acid, caffeic acid, and oleanolic acid has a good anti-RA effect, and the mechanism may be related to the inhibition of TLRs/MAPKs/NF-κB signaling pathways.

Due to the large amount of Codonopsis pilosula planted in Weiyuan county,and the arable land area,the local medicinal materials office uses a large amount of manpower,financial resources and material resources to estimate its area every year. In order to extract the information of local Chinese medicinal materials more quickly and simply,we try to apply remote sensing technology to the extraction of Chinese medicinal materials. This paper will use Weiyuan county of Gansu province as the research area,and use the domestic ZY-3 Satellite multi-spectral remote sensing image as the data source to find out the spectral characteristics of the party's participation in other remote sensing images. The visual interpretation method was used to extract the planting area of the C. pilosula in Weiyuan county. The estimated value of the planting area of C. pilosula using satellite remote sensing technology was 75 965 mu( 1 mu≈667 m²),which was basically consistent with the field survey data of the local medicinal materials office. After the accuracy verification,it was found that the precision of C. pilosula planted by visual interpretation was more than 70%. It is concluded that the satellite remote sensing technology can be used to extract the information of C. pilosula and it can provide the relevant information of the planting area of Chinese medicinal materials quickly and accurately.

Based on¹ H-NMR metabonomics,the effects of Codonopsis pilosula,rice-fried C. pilosula and honey-fried C. pilosula on spleen-asthenia rats were compared,and the mechanism was discussed in this study. The rat model of spleen deficiency was established by weight-bearing swimming and fasting every other day. The effects of different processed products of C. pilosula on the body weight and swimming time of rats were observed. At the end of administration,the gastrocnemius muscle of the right leg of rats was collected and detected by¹ H-NMR,and the mechanism of different processed products of C. pilosula in improving spleen deficiency was preliminarily investigated by multivariate statistical analysis. The results showed that C. pilosula,honey-fried C. pilosula and rice-fried C. pilosula could significantly prolong the swimming time( P<0. 05). There was no significant difference in the body weight of rats with spleen deficiency. The results of metabonomics showed that honey-processed C. pilosula could significantly decrease levels of leucine,isoleucine,alanine,acetate,glutamate,succinate,anserine,dimethylamine,dimethylglycine,creatine,phosphorylcholine,glycerophosphorylcholine,taurine,inosine,fumate,hypoxanthine and lactate,but increase levels of glucose,glycine,compared with model group. Therefore,honey-fried C. pilosula has the best efficacy on spleen deficiency syndrome in rats by regulating glycometabolism,amino acid metabolism,lipid metabolism and nucleotide metabolism.

With the improvement of living standard,the theory of " medicine and food homology" has developed rapidly in the field of diet,medicine and health preservation. In recent years,many literatures have been reported on the active ingredients and pharmacological effects of medicinal and edible plants,but relatively few reports have been reported on their safety investigation. Therefore,to further evaluate the quality and safety of medicinal and edible plants,Astragali Radix,Codonopsis Radix and Laminariae Thallus were selected as our research objects in this study. Moreover,the pollution level and the potential health risk of heavy metals were deeply assessed in different types of medicinal and edible plants. Especially,the contents of chromium,copper,arsenic,cadmium,mercury and lead in these three herbs were determined by inductively coupled plasma mass spectrometry( ICP-MS),and their health risk level was evaluated by target hazard coefficient method. The results showed that under the international heavy metal limit standard( ISO 18664-2015,GB 2762-2017),the over-standard rates were 25%,77% and 100% in 16 batches of Astragali Radix,26 batches of Codonopsis Radix and 9 batches of Laminariae Thallus,respectively. Besides,the values of target hazard quotients( THQ) for adults and children are 0. 028 244,0. 063 505 and 0. 014 485,0. 032 568 in Astragalus membranaceus and Codonopsis pilosula,respectively,which were higher than the standard values of 0. 02 and 0. 011 25. While,the total heavy metals THQ values for adults and children are 0. 023 734 and 0. 020 287 in Laminariae Thallus,which were much higher than the standard values of 0. 008 0 and 0. 007 5. However,the CR values of As,Cd and Pb in the three herbs were lower than 1×10~(-6). Above results indicated that those six harmful elements have certain health hazards to the exposed population,but there is no potential carcinogenic effect. It can be seen that,there were still presence of the pollution of harmful elements,and it is necessary to establish the reasonable limit standards and quality control methods of medicinal and edible plants in time.

GAPDH(glyceraldehyde-3-phosphate dehydrogenase) gene is a key enzyme gene in carbohydrate metabolism and always used as reference gene. To clarify and complete the biosynthetic pathway of polysaccharide, the GAPDH gene in Codonopsis pilosula, named CpGAPDH, was cloned according to the transcriptome of pilosula, using the GAPDH gene in potato as query. The CpGAPDH contained a 1 014 bp open reading frame(ORF) and encoded a protein with 337 amino acids. Bioinformatic analysis clearly suggested that CpGAPDH shared high similarity with GAPDH among other plants, and had the closest relatives to potato and danshen. The predicted protein did not have signal peptide, which indicated that it might be located in the cytoplasm. According to the existing of several phosphorylation sites and the conserved domains analysis, we predicted that it belonged to Gp_dh_N superfamily. Prokaryotic expression showed that the recombinant expressed a 44.3 kDa protein, which was corresponding to the theoretical relative molecular mass. However, the relative transcript level of the CpGAPDH did not have significant differences in different tissues and roots at different developmental stages of pilosula. Moreover, the stability of the CpGAPDH was analyzed by BestKeeper, geNorm, and NormFinder and RefFinder software, which showed that the CpGAPDH was more stable and could be used as a new reference gene. All these lay a foundation for the expression analysis of the gene relative to the polysaccharide synthesis.
